R. T. ADDLESBURGER ATTACHMENT FOR FLUSH TANKS Filed June 4, 1943 Patented Oct. 12, 1943 UNITED STATES iATENT OFFICE 52,331,589 ATTACHMENT FOR FLUSH TANKS Q Roy '1. Addlesburger, McKees Rocks, Pa. Application June 4, 1943, seen-Nanette 6 Claims. (01. 4-228) This invention relates to disinfecting appa- I ratus and has particular reference to an apparatus for disinfecting or deodorizing rooms, by means .of which, volatile disinfectants or subst'ances'producing fragrantodors may b caused to permeate the atmosphere. H

One of the objects of the present invention is to provide a simple attachment. for the flush tank of a toilet whereby the emptying of the tank will cause air to be drawn in over the disinfectant or deodorizingmaterial, and then as the Water rises in the tank, the volatile constituents of such material will be expelled into the room. v v V Another. object is to provide an attachment of the aforesaid character which may be easily and quickly installed without'the use of tools, and when in position, shall not alter the exterior appearance of the flush tank.

A further object is to provide an attachment &

which shall be readily accessible for "removal of the disinfecting or deodorizing material, or for purpose of cleaning, and wherein any moisture or liquid that tends to collectfwill automatically drain into the flush tank.

With the foregoingand other, objects in View,

the invention may be. statedto consist in the various. novelfeatures of construction and arrangement or combination, all of which will be fully described hereinafter and pointed out in the claims.

In the drawing accompanying and forming a part of this application,

Fig. l is a perspective view of a toilet and flush tank equipped with my invention;

Fig. 2 is a top plan view of the flush tank with parts broken away;

Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 2; and

Fig. 4 is a fragmentary vertical sectional view taken on the line 44 of Fig. 2.

The letter A designates generally a conventional flush tank which is operatively connected with the toilet bowl B in the usual manner. The tank A is normally fitted with a removable cover that is replaced in accordance with my invention, with a cover that is similar in exterior appearance.

In adapting my invention to a flush tank of this general character, I provide a removable tray which may be made entirely of ceramic material or of sheet metal having a baked enamel finish, or of any other suitable material. This tray has a bottom wall I0 and upwardly and outwardly extending side walls II and end walls I2 that are adapted to rest on the upper edges of the corresponding walls of the flush tank A. It will be noted that the front wall ll of the tray is preferably bevelled on itstop surface to define one wallof a discharge passage M to be to form a baflle, and immediately'in front there- Cooperating with thejtray'is the cover Cwhich to all outward appearances is identical with the cover that is normally used. However, the under top" surface of this cover is provided. with a plurality of projectionsv 20 that are illustrated as beingdiamond shaped in plan view, and which form-a series of baflles fOI'Qtlle air passing over the deodorant material. the cover is adapted'to lie flush. with the rear, wall llf of the tray and the rear wall of the flush tank',-as illustratedin Fig; 3; Preferably the end walls 22 and the front wall 23 of the cover are turned downwardly and extend a sufficient distance to cover the tray and thus provide a neat appearance. As clearly shown in Fig. 3, the front wall 23 is spaced outwardly a slight distance from the front edge ll of the tray to define the other wall of the air passage it. Also the under surface of the cover adjacent the front edge is recessed to cooperate with the upper beveled surface of the tray front wall H to form a continuation of this passage which communicates with the chamber containing the deodorant material.

In use, no tools are required as the tray and cover may be easily and quickly installed by removing the standard tank cover, then placing the tray in position so as to rest on the top edges of the flush tank. If granular deodorant material is used, it is then sprinkled to a suitable depth in the tray, or if deodorant cakes are used, these are placed in the depressions IS in the tray, after which the cover C is positioned on top of the tray and tank.

The back edge/2| of When the toilet is flushed, the lowering of the level of the water in the flush tank will cause air to be drawn in through passage II as indicated by the arrows in Figs. 1 and 3, then over the deodorant material and through slot l and apertures l1 into the flush tank. As the water level rises in the tank, the flow of this deodorant laden air will be reversed and it will again pass over the deodorant material and then be expelled through passage I4 into the room.

Since most of. the deodorant materials are of a somewhat deliquescent nature, it is desirable to drain the moisture therefrom as it forms. To

this end, I preferably slope the bottom surface I 0 of the tray slightly downwardly toward the rear thereof so that the moisture'thereon will drain through the apertures ll into the waterin the flush tank. This is not only desirable from the standpoint of prolonging the life of the deodorant material, but the water in the tank is mixed with the liquid from the deodorant material and hence the toilet bowl will be deodorized when the toilet is flushed. The apertures l1 also permit the tray to be washed while it re-' mains in position, since the water used for this purpose will drain freely into the flush tank.

What I claim is:

1. An attachment for a flush tank of the character described comprising a tray adapted to be supported by the top walls of the tank, and interposed between the tank and the cover therefor, said cover cooperating with said tray to provide a chamber for deodorant material, said chamber having passages communicating with the interior of the flush tank and with the atmosphere exteriorly of the flush tank.

2. An attachment for a flush tank of the character described comprising a tray adapted to rest on the top walls of the tank, said tray having an aperture formed in the bottom wall thereof and communicating with the interior of said tank, and a cover cooperating with said tray to provide a chamber for deodorant material, said cover and tray having spaced walls defining a passage from said chamber to the atmosphere exteriorly of the flush tank.

3. An attachment for a flush tank of the character described comprising a tray adapted to rest on the top walls of said tank, said tray having an aperture formed in the bottom wall thereof and communicating with the interior of said tank, a cover cooperating with said tray to provide a chamber for deodorant material, and a plurality of baflies in said chamber for directing the air in a torturous passage over the deodorant material, said cover and tray having spaced walls defining a. passage from said chamber to the atmosphere.

4. An attachment for a flush tank of the character described comprising a tray adapted to be supported by the top walls of the tank, a cover cooperating with said tray to provide a chamber for deodorant material, said cover having walls extending downwardly and overlapping said tray to conceal the same, and one of said walls being spaced from said tray to provide a passage from said chamber to the atmosphere.

5. An attachment for a flush tank of the character described comprising a tray having marginal walls adapted to rest upon the top walls of the flush tank and lie substantially flush with the side walls thereof, said tray having its bottom surface depressed below the plane of the top walls of said tank and being provided with an elongated aperture adjacent the rear edge thereof communicating with the interior of said tank, and a cover adapted to overlie said tray and having depending walls overlapping the marginal walls of the tray to conceal the same, said cover cooperating with said tray to provide a chamber for deodorant material, and one of said depending walls of the cover being spaced from said tray and flush tank to provide a passage from said chamber to the atmosphere.

6. An attachment for a flush tank of the character described comprising a tray having marginal walls adapted to rest upon the top walls of a flush tank and lie substantially flush with the side walls thereof, said tray having its bottom surface depressed below the plane of the top walls of said tank and being provided with an elongated aperture adjacent the rear edge thereof communicating with the interior of said tank, the bottom surface of said tray being sloped downwardly toward the rear thereof and being provided with a baflle along the front edge of said aperture and a plurality of smaller apertures in front of said baille, and a cover adapted to overlie said tray and cooperating therewith to form a chamber for deodorant material, said cover and tray having spaced walls defining a passage connecting said chamber with the atmosphere.
